John, Not sure that changing filter caps will help theheadphone hum. Biggest problem is that new headphones respond to very low freq. I played with my R4B for a long time before I threw in the towel and built an audio filter. Best I can tell, it will be more a function of headphones then your power supply filters. 73, Ron
